Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stacker bundler for collecting and binding signatures conveyed from a printing device.

[0002]

2. Description of the Related Art Conventionally, a stacker bundler has been used as a device for accumulating and binding signatures discharged from a printing device. As shown in FIG. 6, the stacker bundler 51 includes a belt conveyor 52, a press roller 53, a separating device 55, a small bundle stacking device 57, and a large bundle stacking device 59, which are arranged from upstream to downstream. The signatures are processed as follows.

First, a signature S discharged from a printing device (not shown) is conveyed by a belt conveyor 52, and after passing through a press roller 53, folds are arranged, and then conveyed to a severing device 55. . Separation device 55
Is provided with a roller 61 that is swingably supported in the vertical direction. The roller 61 temporarily blocks the flow of the signature S and forms a gap in the flow of the signature S. Thus
The signatures S are intermittently discharged from the separating device 55 to the downstream side, discharged from the nip rollers 63, and then stacked on the temporary receiving plate 65 of the small bundle stacking device 57. When a predetermined number of copies of the signatures S are collected and a small bundle is formed, the temporary receiving plate 65 withdraws from the temporary receiving position in the gap of the flow of the signatures S, and the small bundle moves downward from the temporary receiving plate 65. It is transferred to the elevator 67 provided. This small bundle is the elevator 6
After being lowered to the lower part of the small bundle stacking device 57 by 7, it is pushed out horizontally by the pusher 69 and transferred to the turntable 71. Subsequently, if necessary, the signatures S are half-turned on the turntable 71 so that the signatures S are alternated, and then sent to the large bundle stacking device 59, where a predetermined number of small bundles are stacked to form a large bundle. To be done.

As shown in FIG. 7, the small bundle stacking device 57 is
It is provided with a pair of guide plates 73 that guide both sides of the signature S and align the positions of the signature S in the width direction, and the temporary receiving plate 65 described above. The guide plate 73 is divided into an upper plate portion 73a and a lower plate portion 73b via a slit 75, and the upper plate portion 73a and the lower plate portion 73b are connected by a connecting member 81 having a U-shaped cross section. Also, this guide plate 73 is a signature S
The interval can be adjusted according to the width of.

The temporary receiving plate 65 is configured to be movable back and forth with respect to the slit 75 of the guide plate 73 by the cylinder 83, and temporarily receives the signature S at the temporary receiving position which has entered the slit 75 shown in FIG. In this way, by forming the slit 75 into which the temporary receiving plate 65 can enter into the guide plate 73,
The spacing between the guide plates 73 can be adjusted within the width of the temporary receiving plate 65, and it is possible to accommodate signatures S having various widths.

[0006]

However, as shown in FIG. 8, when the temporary receiving plate 65 is withdrawn from the temporary receiving position and the small bundle is transferred to the elevator 67, the slit 75 is opened. The signature S may enter the slit 75 and stick out to the outside of the guide plate 73, which causes a problem that the signature S cannot be accurately aligned. To solve this, for example, with the bristling part facing downward, insert the brush into the slit, when the temporary receiving part enters, push and bend the bristles of the brush, and after leaving, straighten the bristles of the brush. A method has also been proposed to prevent the signature from protruding by returning to the slit and closing it, but if the brush bristles are deformed and cannot return to the original shape, the signature may protrude, and It could not be said that the prevention of entry was reliable. Further, due to this, it is necessary to frequently replace the brush, which causes a problem of high maintenance cost.

The present invention has been made to solve the above problems, and in a small-bundle stacking device, when the temporary receiving plate exits from the slit, the signature is surely prevented from entering the slit. However, it is an object of the present invention to provide a stacker bundler capable of accurately aligning signatures.

[0008]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a transport device for transporting signatures in a state where they are horizontally offset and overlapped with each other, and a flow of signatures transported on the transport device. A severing device that temporarily holds the creases to form a gap in the flow of signatures, a small bundle collecting device that receives signatures discharged from the severing device, accumulates them in a predetermined number and conveys them downward, and the small bundle accumulating device. In a stacker bundler provided with a large bundle producing section for discharging and accumulating small bundles of signatures accumulated in the above, in the small bundle accumulating device, a slit extending in the horizontal direction is formed, and both sides of the conveyed signatures are formed. A pair of guide plates that extend along the signature transport direction so as to guide, a temporary receiving plate that is configured to be movable back and forth with respect to the slit and that enters the slit to temporarily receive the signature, and the temporary receiving plate When exiting from the slit A shutter member that closes at least a part of the slit in the height direction of the slit, and the shutter member is pushed by the temporary receiving plate when the temporary receiving plate enters and moves by the temporary receiving plate.

On the other hand, as shown in FIG. 5A, when the temporary receiving plate 65 enters, the temporary receiving plate 65 holds the shutter member 3 in place.
While pushing the shutter member 3 upward by slidingly contacting the lower surface thereof, the shutter member 3 enters a predetermined temporary receiving position. The shutter member 3 pushed upward is positioned on the upper surface of the temporary receiving plate 65 in a state where the engaging portion 5 is engaged with the first cutout portion 7.

As described above, according to this embodiment, since the shutter member 3 is swingably supported on the outer surface of the guide plate 73, when the temporary receiving plate 65 is retracted from the slit 75, the shutter is released. The member 3 swings downward due to its own weight, and a part of the slit 75 is closed in the width direction. As a result, the signature S can be prevented from protruding outside the guide plate 73 through the slit 75. On the other hand, when the temporary receiving plate 65 enters the slit 75, the shutter member 3 is swung upward while slidingly contacting the temporary receiving plate 65, so that the temporary receiving plate 65 is not hindered from entering. The 65 can smoothly enter the temporary receiving position. As described above, in the present embodiment, the structure is simple, the cost is low, and the operation of the temporary receiving plate 65 is not hindered.
It is possible to reliably prevent the signature S from protruding.

Further, since the engaging portion 5 is provided with the surface 5a which is flush with the inner surface of the guide plate 73 in the state of being engaged with the first or second cutout portions 7 and 9, the signature S is Surely prevent it from protruding into the slit 75, and
Can be accurately aligned along the inner surface of the guide plate 73.

In the above embodiment, two shutter members 3 are provided on each guide plate 73, but the number of shutter members 3 is not limited to this, and the guide plate 7 is not limited to this.
It may be appropriately determined according to the length of 3 or the like.

Further, in the above embodiment, the guide plate 73 is divided into two via the slit 75, but the guide plate 73 is divided.
Does not necessarily have to be divided, and a slit that allows the temporary receiving plate 65 to enter can be formed.

In the above embodiment, the shutter member 3 is supported by the guide plate 73, but the present invention is not limited to this. For example, the shutter member 3 may be supported by the connecting member 81.
Alternatively, it may be supported by another member movable together with the guide plate 73.

Further, in the above embodiment, the slit 75 is closed by swinging the shutter member 3, but
The slit 7 is not limited to this.
It suffices if it is configured to be movable so that 5 can be closed in the height direction. For example, the shutter member 3 may be supported so as to be vertically movable. In this case, for example, the guide plate may be provided with a slit extending in the vertical direction, and the shutter member may be supported along the slit so as to be movable in the vertical direction.

The material forming the shutter member 3 is not particularly limited, but it is desirable to use a synthetic resin such as MC nylon so as to make a smooth sliding contact with the temporary receiving plate 65. Alternatively, the shutter member 3 may be covered with a fluorine resin or a silicone resin.

[0021]

As is apparent from the above description, the stacker bundler according to the present invention includes the shutter member that closes the slit in the height direction when the temporary receiving plate is retracted from the slit. Therefore, the signature guided by the guide plate can be prevented from protruding from the slit to the outside of the guide plate. On the other hand, when the temporary receiving plate enters the slit, the shutter member is pushed and moved by the temporary receiving plate, so that the temporary receiving plate can be smoothly moved to the temporary receiving position without obstructing the temporary receiving plate. Therefore, according to the present invention, it is possible to reliably prevent the signature from protruding with a simple structure and at low cost without hindering the operation of the temporary receiving plate.

Further, since the engaging portion engages with the notch formed in the guide plate and has a surface which forms the same plane as the inner surface of the guide plate, the signature is sure to stick out into the slit. In addition, it is possible to accurately align the signatures along the inner surface of the guide plate.
